In addition to the -7 I posted earlier and a SDS in .45 Colt, I have a number of the garden variety .45 ACP 625s in 3, 4, and 5." This one's my 625-2 shooter I call the "ugly gun"--a concession to my failing eyesight. A friend (thanks Leonard) sent me the rear sight with red elements. I had the taller red front sight, so I changed the rear elements to green to get some contrast. The combination works very well for me. The gun has great single and double action, an overtravel stop, and it's very accurate. It had the Grippers on it when I got it, and after trying them, saw no reason to change. One of my favorite shooters.

Fuzzy but workable sight alignment.
